Seattle-area transient Gary Sandford Raub, 64, was arrested in October in connection with the death of Blanche M. Kimball. The 70-year-old woman’s body was found in her State Street home on June 12, 1976.

Raub was expected to be returned to Maine in December, but Maine Department of Public Safety spokesman Stephen McCausland said earlier this month that a last-minute health issue had delayed his transport.

A Kennebec County Jail administrator confirmed Sunday afternoon that Raub had arrived and is being held without bail. He is scheduled to be arraigned Monday at Augusta Superior Court for the murder charge.

The man, who was going by the name Gary Robert Wilson in 1976, was tied to the cold murder case through DNA evidence after he took part in an undercover “chewing gum survey” in Seattle that police staged in July, according to documents filed in Kennebec County Superior Court.

Raub had rented a room from Kimball in 1976 and was the prime suspect in her murder from the beginning, according to the affidavit. He denied involvement in her death and left the state a few years after the murder.

He surfaced this fall in Seattle after he was suspected in the stabbing of another transient. Maine State Police Detective Abbe Chabot, who had taken over the cold case in 2003, worked with Seattle police to match blood from the knife used in the west coast stabbing to blood found at the Augusta murder scene.

In July, a Seattle police detective posed as a market researcher and asked Raub to participate in a “chewing gum survey,” for which he would be paid $5. Raub agreed, according to the affidavit. The gum he chewed was sent to the Maine State Police Crime Lab, where investigators concluded that the DNA matched a blood drop found on the kitchen drawer of Kimball’s residence after her murder.

His arrest marks the record for the oldest cold case arrest in Maine history.
